Microcontrollers include transmitter functionality

This AVR range offers RF performance operating in the licence-free ISM frequency bands (868MHz to 928MHz, 433MHz, and 315MHz).

With a low-power AVR CPU, an effective RF transmitter and a sleep-mode power consumption of 160nA, the ATA874x range is optimised to address battery-driven applications such as remote controls or garage door openers.

The QFN24 packages measure 5mm x 5mm to allow the creation of extremely small designs at competitive costs.

The ATA874x devices offer maximum flexibility using the ATtiny44V CPU, allowing in-system flash memory reprogramming.

By executing instructions in a single-clock cycle, the ATtiny44V achieves throughputs approaching one MIPS per MHz that enable system designers to optimise power consumption versus processing speed.

The AVR controller can simplify hardware and software designs.

Customers that have worked with AVR or earlier RF products can reuse existing RF transmitter or AVR designs and software, thus reducing development costs and time to market.

The ATA874x single-chip narrowband transmitter range complements the Atmel ISM-band receivers, such as ATA8201 and ATA8202 or ATA8203/4/5, providing a total end-to-end solution.

To simplify and accelerate product design, a complete design kit for uni-directional RF applications, as well as Atmel's AVR Studio for new software development (STK512-EKx-IND), are available for customer lab measurements and performance evaluations.
